Strange Day Good Day

[laowho]

Doug--You're way over thinking this. In a nutshell, its about the quality of your sight picture--how well you are seeing--and harmonics. Some bullets are better than others in a given barrel, and it is a waste of time trying to make a rifle shoot some bullets. The rifle will tell you what it wants.

As a rule of thumb, a 45 caliber Shiloh will want to shoot with a 457132 Lyman Postell and 69 or 70 grains of 2f. If you are shooting paper patch, you want a bullet 1.3inches long and 70 grains of powder. They don't call them 45-SEVENTYS for nothing. Shoot straight, rdnck.

Hi rdnck, Dunno about the over-thinking part...Over-reachin maybe, if I'm tryin to chase more than 1 tail at a time, but over-thinking? Harmonics reach pretty deep seems to me, and deeper still may be tryin to tease out wh/ parts of it are more and less applicable to BPCR than to other forms. But if you're right about that, then I'll be glad for the respite if this can teach me it, cuz thinkin is sumthin I generally do too much of, so good call.

The 132 I have and have cast--they're next for laddering. Right now I'm still zeroing in on the Saeco 645 that I cast. Best I can tell from previous sessions, it likes 68 gr 1.5F Swiss. That was set back (speakin of harmonics), so now I'm just tinkering w/ movin the bullet forward to full kiss on the lands. Trying to avoid resorting to QuickLoad and the Optimum Barrel Time spread sheet--would rather get my harmonics the old-fashioned way. Learnin to do this w/ a free-floating bullet has improved my loading a bit, too--gettin to know that round and the rifle's innards a bit better. Gotta say, it's pretty satisfyin knowin exactly where I am with everything. Otherwise, "Anything worth doing is worth doing badly." Cheers, Doug
